Zac Brown ditched the boots for dress shoes last night to honor a music legend.

Some of music's best performers from all genres came together to remember Frank Sinatra and his 100th birthday.

The televised special "Sinatra 100: An All-Star Grammy Concert" featured some great performances.

One of those came from Zac Brown, as he performed Sinatra's classic "The Way You Look Tonight".

Check out the performance!
